Red List Status -

Endangered (EN) , assessed in 27/10/2017

Phyllanthus pilifer var. pilifer is endemic to New Caledonia, where it is restricted to the northwest of Grande Terre. This shrub is found in forest undergrowth or riverine vegetation on ultramafic substrate between 50 and 350 m asl. Known from two locations, its extent of occurrence (EOO) and area of occupancy (AOO) both equal 8 km². The main threats are mining activities and uncontrolled bushfires. Therefore, P. pilifer var. pilifer is listed as Endangered (EN) under criteria B1ab(ii,iii,v)+2ab(ii,iii,v).

Geographical area


P. pilifer var. pilifer is endemic to New Caledonia, where it is restricted to the northwest of Grande Terre (Kaala and Koniambo massifs).

Population


Population size is unknown.

Habitat


P. pilifer var. pilifer occurs in forest undergrowth or riverine vegetation on ultramafic substrate between 50 and 350 m asl.

Threats


The main threats are uncontrolled bushfires and mining activities at Boualoudjelima (SLN) and Koniambo (KNS).

Conservation


P. pilifer var. pilifer is protected by legislation in Province Nord, but does not occur in any protected areas. This taxon would benefit from ex situ and in situ emergency conservation actions. It is recommended to monitor and preserve known populations in delimited areas of the mining site, and to inform the local authority responsible for the coordination of the firefighting effort about the presence of the taxon in the concerned areas. It would also be advised to run multiplication tests in order to assist future planting operations. Finally, prospection in the valleys of the Koniambo, Kaala and Tiébaghi massifs is needed to better estimate the size of the population et and understand potentiel threats.
